“As of October 2013, DHS estimates it had approximately 159 million rounds in inventory, enough to last about 22 months to meet the training and operational needs of its firearm-carrying personnel.”
From the article..
22 mo’s is 1.83 years. 159,000,000 rds divided by 1.83 is 86,885,245 per year. Divide that by 1300 rds, rds need per armed personnel. What do you get?
6,681,000 armed homeland security personnel....Really?
Your 1300 number is off by a big bunch. Weapons training with a full auto will burn that up in a couple of hours.
